Abstract
A band pass filter circuit for transmitting electromagnetic signals within a desired frequency band includes a transmission line extending between input and output terminals, a high pass filter connected to the transmission line for blocking the transmission of signals falling below the operational frequency band, and a low pass filter connected to the transmission line for blocking the transmission of signals falling above the operational frequency band. Additionally, a primary suppressor connects the transmission line to ground and suppresses unwanted transients on the transmission line. A set of supplemental suppressors connects the transmission line to ground and suppresses any residual transient energy on the transmission line after treatment by the primary suppressor. Each supplemental suppressor is paired in parallel with a higher-valued capacitor from the low pass filter in order to minimize the effect of its parasitic capacitance on the band pass characteristics of the circuit.
